Surveying And Mapping

WestLAND Group’s core competency of surveying and mapping is the basis for the broad menu of services WLG offers today. The complete, accurate information we provide through traditional ground-based techniques and cutting-edge geolocation and aerial technology lays the foundation for solid design, efficient construction and successful projects.

Construction Support

Cerritos Channel Survey | Southern California Edison and Port of Long Beach | Terminal Island, CA

Larger container vessels and increased ship traffic at the Port of Long Beach have required extensive modifications to the port’s main waterway and electrical infrastructure. Working closely with SCE and Port Operations, WestLAND Group precisely mapped the Cerritos Channel and Edison’s electrical facilities, and provided construction support to insure the smooth flow of cargo through this crucial part of the U.S. supply chain.

Red Bluff Substation | Southern California Edison | Red Bluff, CA

WestLAND Group has played an instrumental role in the reinforcement of the region’s electric grid. Working in collaboration with Southern California Edison, our survey teams document boundaries and rights-of-way for new substations and transmission lines to improve the grid’s resilience, stability and readiness for California’s electrified future.

Irwindale Pit Mapping | City of Irwindale | Irwindale, CA

WestLAND Group conducts open pit mining surveys to map the City of Irwindale’s extensive rock quarries. Using photogrammetric and bathymetric surveys, conventional and GPS/GNSS techniques, WLG produces accurate lake bottom profiles and color-coded maps used to estimate underwater material extraction, confirm slope stability, and compare material removal volumes year over year. Topographic and boundary survey maps at 11 locations within the city will be used to facilitate pit reclamation for recreational and other uses in the future.

LiDAR and 3D Laser Scanning

WestLAND Group’s Laser Scanning and 360-degree video capabilities guarantee accurate data capture of construction routes and facilities. These datasets, gathered with our arsenal of ground or aerial-based technology, can be used for compliance verification or future retrofit and upgrade studies. Such cutting-edge equipment offers a significant cost saving over deploying crews to physically capture the data.

Pipeline Survey | SoCalGas | Los Angeles County, CA

California’s dynamic geography requires gas utilities to maintain precise location information for all wells, pipelines, and fittings. SoCalGas relied on WestLAND Group’s photogrammetry and GIS expertise to develop 3D Digital Terrain Maps pinpointing equipment locations. The sophisticated maps are used to study the feasibility of automated hydraulic modeling for new pipeline design, improving safety and gas delivery.

Los Coyotes Water Reclamation Plant | Los Angeles County Sanitation Districts | Cerritos, CA

The LACSD hired WestLAND Group to precisely map underground galleries at its Los Coyotes Water Reclamation Plant, so engineers could design electrical conduit routes and conduct conflict analysis. WLG crews provided high-resolution laser scans of approximately 550 feet of tunnels and galleries–all in one day rather than the five to six days a traditional survey would have required. The full survey control report and 3D point cloud of the large data set are easily accessible for convenient, in-office measurements.

Unmanned Aerial Systems (UAS)

WestLAND Group is a pioneer in the use of Unmanned Aerial Systems and Vehicles to improve the accuracy, cost-effectiveness and safety of data gathering at large or remote project sites. UAV’s provide high-resolution images using GPS coordinates, and can be used to create 3D Point Clouds and Digital Terrain Models. All WLG pilots have the necessary FAA licenses to operate UAV’s for geospatial services.

Facility Inspections

Liebre Span Inspection | SoCalGas | Gorman, CA

WestLAND Group’s UAV team has conducted many compliance inspections for major utility companies. Our pilots routinely operate these aircraft safely at remote facilities like this high-pressure gas pipeline in earthquake-prone Gorman. UAV inspections are inherently less dangerous to conduct than physical inspections and gather significantly more data than methods relied on in the past.

UAS Aerial Scanning

Mitsubishi Cement Plant | Lucerne Valley, CA

The Mitsubishi Cement Corporation needed to document existing facilities at its Southern California plant to facilitate new construction. WestLAND Group UAV team laser-scanned 4 acres of the facility, including a tower whose 30-foot diameter pipe is used to preheat materials for combustion. WLG provided a point cloud of 30+ scans and 3D modeling of the tower’s structural beams so engineers could design a new catwalk near the tower’s access hatch for kiln sampling and environmental compliance.
